What happens if you completely stop drinking water?
In this data comparison timeline video, we track how dehydration affects the human body hour by hour and day by day, starting from mild thirst and ending at critical organ failure and death.
This timeline is based on a healthy adult, under normal climate conditions, with low physical activity and no medical intervention.
Each entry compares time without water as the main metric, showing how dehydration progressively impacts the brain, blood, heart, kidneys, and other vital organs.
The video also includes comparison cases—such as hot climates, heavy activity, children, elderly people, and medical conditions—to show how survival time can change. Watch till the end to understand how long the human body can truly survive without water.

Timelines are approximate averages and can vary greatly based on environment, health, age, and activity level.
